Description

LED fluorescent lamp device capable of directly replacing fluorescent lamp

Technical field

The utility model relates to the technical field of illumination, in particular to an LED fluorescent lamp device which can directly replace a fluorescent lamp.

Background technique

The traditional fluorescent tube is also called fluorescent lamp. As shown in Fig. 3, there is a filament at each end of the tube. The tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the tube is coated with phosphor, between the two filaments. The gas emits ultraviolet light when it conducts electricity, so that the phosphor emits visible light. Due to the heavy metal pollutant "mercury", the environmental pollution of the discarded fluorescent tube is very serious.

LED fluorescent lamps use LEDs as the light source, which is more efficient, more energy efficient, has a longer service life, and is more environmentally friendly. LED fluorescent lamps can save more than 70% of electricity, and the lifespan is more than 10 times that of ordinary lamps. It is almost maintenance-free. There is no problem of frequent replacement of lamps, ballasts and starters. The cost savings can be reduced in about half a year. Exchange back the cost. It is the ideal product to replace fluorescent tubes at this stage.

In the prior art, as shown in Fig. 4, almost all LED fluorescent lamps on the market are LED fluorescent lamps 19 with built-in power. The so-called built-in power supply means that the power is placed inside the lamp. The biggest advantage of this built-in type is that it can be made to directly replace the existing fluorescent tube without any modification to the original circuit. For example: Chinese utility model patent No. 201 120020876. 4 discloses "an LED lamp with a starter", and its technical solution includes an LED lamp tube and an LED starter, and each end of the LED tube is provided. There are two terminals, two terminals on one end of the LED tube are short-circuited, and the two terminals on the other end are discrete terminals, one of which is used to connect with one power supply line, and the other is connected to the LED starter. One shorted terminal is connected, and the other shorted terminal is connected to another power incoming line. The LED tube and the LED starter are mounted on the two-terminal type lamp holders. The LED lamp with the starter can be compatible with the traditional two-end line type lamp holder. The lamp uses a built-in power supply.

However, this power supply built-in LED fluorescent lamp has the following disadvantages: (1) It is difficult to replace the power supply. The service life of the LED is much longer than the service life of the power supply. If the power supply is broken, directly replacing the entire LED fluorescent lamp will result in great waste. If only the power supply is replaced, it is necessary to rely on the professional to disassemble and replace the circuit; (2) affecting the LED illumination the quality of. The heat emitted causes the LED fluorescent lamp to produce glare, dark shadow and light out of uniformity during use; (3) poor heat dissipation. Since the power supply is built-in, the heat of the power supply is added to the lamp, which makes the heat dissipation of the LED more difficult and shortens the service life of the LED. (4) The recycling cost is high, and the built-in power supply also increases the recycling of electronic waste. The cost of processing, because the power supply must be removed and processed separately; (5) It is difficult to meet the safety standards. Due to the built-in power supply, it has a great impact on meeting safety standards.

The utility model patent of the application No. 200920134372. 8 discloses "an LED fluorescent lamp with an external LED power supply", which comprises an LED fluorescent lamp body, and an external LED power supply is connected to the LED fluorescent lamp body, and the external LED is connected. The power supply includes a PCB circuit board, input and output terminals, and a power supply box. The PCB circuit board is built in the power supply box, and the input terminal is connected to the LED fluorescent body through the PCB circuit board and the output terminal. Although the LED fluorescent lamp of the external LED power supply solves some defects existing in the power supply, the power supply installation needs to change the original circuit to fix it on the lamp board of the conventional fluorescent lamp.
